TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 557,913, dated April 7, 1896.

Application filed July 31,1895. Serial No. 557,680. (No model.)

T0 ctZZ whom it may 'conoer'n:

Be it known that I, ANDREW W. SrEIeER, a citizen of the United States, residing in Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Type-WVriting Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to an improvement in type-writing machines; In the use of such machines the attention of the operator is necessarily kept more or less on the keyboard of the machine, in consequence of which fact the paper-carriage would often reach the end of the line without his becoming aware of the fact were not some means provided to attract his attention. It has also been found very convenient,if not absolutely necessary, to provide a positive stop for the carriage when it has reached the end of the line. It has also been found of advantage to provide mechanism whereby the type-bars will be automatically locked when the carriage has reached the end of the line to prevent the impression of more than one type upon the final or last point reached on the line. It is to these fea tures of a type-writing machine that my invention applies, with the additional advantage that in my device there is but one adjustment to make, and the alarm, stop, and lock will operate at any predetermined point on the line of writing, While, should the operator so desire, by a depression of an appropriate finger-key or button on the machine the stop and lock will be thrown out of connection with the carriage and further movements will be permitted forthe impression of more letters and characters on the same line. The several parts of my invention are illus' trated in the accompanying drawings, in which Figure 1 is a general plan view of a writing-machine embodying my invention, some of the type-bars being omitted. Fig. 2 is a side elevation of the machine shown in Fig. 1, portions of the frame being broken away to better illustrate my invention. Fig. 3 is a detached perspective view of the paper-car riage and the several parts thereof. Fig. 4

is a detached view of one portion of the mechanism hereinafter fullydescribed.

In the drawings, 5 is the base of the machine, to which are secured the upright standards 6 6, upon which are mounted the typebasket 7, the inkpad ring 8, and the paper carriage 9, which slides upon the guide-rail l0 and the shift-rail 11 to carry the paper upon its platen 12 under and past the printing-point 13.

Immediately below the sliding carriage and 7 extending parallel thereto is a grooved rod 14:, extending from side to side of the machine, supported by socket-brackets 15, Fig. 4;, so as to have a limited end-toend motion, also capable of being rotated in its supports. Upon this rod 14 is mounted a sleeve 16, capable of sliding from end to end and provided with a set-screw 45, working through one side of it and into the groove 17 of the rod 14, so that when the set-screw is loosened the sleeve may move freely along the rod without turning on it, but when the screw is tightened the sleeve will be locked fast .to the rod. Upon this sleeve 16 is an upwardly-extending lug or stop 18, standing in the path of a stop 19, attached to the frame of the paper-carriage.

It will be readily understood that as the carriage is fed along in printing the stop 19 will come in contact with the lug 18 and the rod 14 will be drawn along with the carriage till the limit of its movement is reached, when both the rod and the carriage will be stopped.

lxtending downwardly from the rod 14:, and preferably near one end thereof, is an arm 20, mounted to turn thereon by means of a sleeve 21 and prevented from sliding by the collars 22 and the set-screws 23, so that when the rod is moved longitudinally the arm 20 must move with it. The lower end of the arm 20 is made to bear against a lever 24, preferably by resting in a notch 25 in an arm 26 projecting i therefrom.

The lever 24 is pivoted to the base of the machine at 27 and is pivotally connected at its forward end 28 to a comb-shaped plate 29, extending across the machine immediately beneath the key-levers. This combplate is mounted to the frame of the machine to have a sliding lengthwise movement across the under side of the key levers, and the notches 30 in the plate are of a size to match the thickness of the key-levers and are spaced at an equal distance apart with the key-levers, so that the notches may be moved to register with the levers, or they may be moved out of register, so that the solid parts of the comb will stand immediately under the bars or levers, and thus prevent their being depressed. These parts are so adjusted that when the stop is in its normal position the openings in the comb will stand under the key-levers, and it isheld in such position by means of a spring 31, one end of which is attached to the arm 20 and the other end to the frame of the machine. It will be understood that when the carriage has moved far enough to bear against the stop 18 and move the rod 14 the comb 29 will be thereby moved over till its solid portions come under the key-levers, and they will thereby be locked, and thus prevent the impression of another letter or character on the paper carried along by the paper carriage. When, after the carriage has been stopped and the key-levers locked, it is desired to print more characters on the line just written, the carriage and key-levers may both be released by means of a fingerkey or button 31, mounted on a lever 32, pivoted to the frame of the machine at 33 and connected by a rod 34 to a crank-arm 35, attached to the rod 14 by means of one of the set-collars 22. A depression of the fingerkey 31 will, through its lever and connectingrod, rotate the rod 14 to move the stop 18 on the sleeve 16 out of the path of the arm 19 on the carriage. This will allow the spring 31 to act on the rod 14 and the lock-comb 29, so as to return them to their normal position, when the writing can be continued.

In order to provide an alarm to notify the operator when he has nearly reached the end of a line, a bell 36 is mounted on the adjustable sleeve 10 by means of abracket 37. Upon the bracket 37 is pivoted a bell-hammer 38, provided with a spring 39 to draw it toward the bell to make the stroke when it is tripped. A trip-piece 40 is pivoted at the same place 41 as the hammer 38 and is made to extend upwardly and to terminate in the arm 42, lying normally in the path of the arm 19 on the paper-carriage. This trip-piece is capable of swinging in one direction independently of 'the bell-hammer, but is returned from this movement by a light spring 43, attached at one end to it and at the other end to the sleeve 16. The movement of the trip in the other direction will carry with it the bell-hammer by reason of the lug 44, projecting from its lower end into the path of the bell-hammer.

As the carriage during the process of printing is carried along the arm 19 thereon bears upon and pushes down the trip-arm 42 and the hammer is lifted from the bell against the action of the spring 39. \Vhen the arm 19 on the carriage has passed the arm 42 and released it, the spring 39 draws down the hammer against the'bell and the alarm is sounded.

On returning the carriage the arm 19 thereon bears upon and pushes down the arm 42 and the trip 41 without affecting the bell-hammer 38, and, after the arm 19 has passed, the spring 43 returns the trip to its normal position.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a type-writing machine, the combination of a frame, a moving paper-carriage mounted on said frame, ways disposed in alinement on said frame parallel with said carriage, a longitudinal slide-rod mounted in said ways parallel with the carriage, key-levers, a lock for said key-levers, intermediate mechanism between said slide-rod and said look, a stop on said rod, and a trip on said carriage adapted to engage said stop, the engagement of the stop serving to slide said rod, and the sliding of the rod serving to operate said lock, substantially as described.

2. In a type-Writing machine, the combination of a frame, a paper-carriage mounted thereon, a sliding rod also mounted on said frame, key-levers, a lock for said key-levers, intermediate mechanism between said sliderod and said lock, a stop on said rod, a trip on said carriage adapted to engage said stop, the engagement of the stop serving to slide said rod and the sliding of said rod serving to operate said look, a key mechanism for rocking said rod to take said stop out of the path of said trip, and means for restoring the rod and lock to their normal positions.

3. In a type-writing machine, the combination of a frame, a moving paper carriage mounted on said frame, a sliding rod also mounted on said frame, key-levers, a sliding comb disposed under said key-levers and adapted to serve as a lock therefor, intermediate mechanism between said slide-rod and said comb, a stop on said rod, and atrip on the carriage adapted to engage said stop, the engagement of the stop serving to slide said rod, and the sliding of the rod serving to slide said comb to lock said type-bars.

4. In atype-writing machine, the combination of a frame, a moving papercarriage mounted on said frame, a sliding rod also mounted on said frame, key-levers, a lock for said key-levers, intermediate mechanism between said slide-rod and said look, a stop on said rod adjustable longitudinally thereof, means for preventing axial adjustment of said stop on said rod, and a trip on said carriage adapted to engage said stop, the engagement of the stop serving to slide said rod, and the sliding of the rod serving to operate said lock.

5. In a type-writing machine, the combination with the key-levers of a comb-shaped plate mounted on the frame and having a longitudinal movement across the under side of the key-levers, andhaving the teeth spaced as described, that the teeth and notches will register with the key-levers, and thus as the plate is moved will permit or prevent the mounted on'said frame, a sliding rod also movement of the levers, a rod having a longitudinal movement under the papercarriage, a stop on said rod so located that when in its normal position the notches in the comb will stand under the key-levers, a sleeve loose on the rod, fixed sleeves on each side of the rotatable sleeve, an arm projecting from said loose sleeve, a lever connecting said arm to the movable comb, and a spring acting to maintain the notches in the comb under the key-levers substantially as set forth.

6. In a type-Writing machine, the combination of a frame, a moving papercarriage mounted on said frame, and provided with fixed sleeves and with a loose sleeve between said fixed. sleeves, key-levers, a lock for said key-levers, an arm projecting from said loose sleeves, pivots connecting said arm with said lock, a stop on said rod, a trip on said carriage adapted to engage said stop to move said rod, an arm-carrying sleeve to operate said lock, and means for retracting said rod.

-to engage said stop tolmove said rod, an arm carrying a sleeve to operate said lock, means for retracting said rod, a lug on said loose sleeve, and a key mechanism connected with said lug for oscillating said sleeve to release said look.
